Find X, Y And Z. I Really Need Help!

Answers

Answer 1

Answer:

x = 74°y = 37°z = 25°

Step-by-step explanation:

x° and 106° are same side interior angles, meaning they're supplementary and adds up to 180°. Therefore, you can find the value of x by:

[tex]x+106=180\\\\x=180-106=74[/tex]

x° and 2y° are corresponding angles, meaning they're equal. Therefore, you can find the value of y by:

[tex]x=2y\\\\2y=74\\\\y=\frac{74}{2} =37[/tex]

(4z + 6)° and the angle adjacent to x° are corresponding angles, meaning they're equal. Therefore, you can find the value of z by:

[tex]4z+6=180-x\\\\4z=180-74-6\\\\4z=100\\\\z=\frac{100}{4} =25[/tex]

Factorize 6pq-3rs-3ps+6qr
with solutions ​

Answers

3 (2q - s)(p + r) is the factor form of expression 6pq-3rs-3ps+6qr.

What is Factor?

A factor is a number that divides another number, leaving no remainder

The given expression is 6pq-3rs-3ps+6qr

We need to factorize the expression.

6pq-3rs-3ps+6qr

= 3 (2pq - rs - ps + 2qr)

= 3 (2pq + 2qr -ps - rs)

= 3 (2q(p + r) -s(p + r))

= 3 (2q - s)(p + r)

Hence, 3 (2q - s)(p + r) is the factor form of expression 6pq-3rs-3ps+6qr.

In a scene from a television show, a van rolls down an incline and off a vertical cliff, falling into a valley below. The van starts from rest and rolls down the incline, which makes an angle of 18.0° below the horizontal, with a constant acceleration of 2.90 m/s2. After rolling down the incline a distance of 40.0 m, it reaches the edge of the cliff, which is 45.0 m above ground level.

What is (5,-3) & (4,0) in slope intercept form?

Answers

The slope-intercept form of (5,-3) and (4,0) is y = -3x + 12.

The slope intercept form is simply writing an equation of a line so that the slope or steepness and y-intercept i.e. where the line crosses the vertical y-axis are immediately apparent.

The slope-intercept equation is y = mx + c, where x and y are two variables, and m is slope.

Slope m = [tex]\frac{y2-y1}{x2-x1}[/tex]

Let,

(x1, y1) = (5, -3)

(x2, y2) = (4, 0)

Slope (m) = [tex]\frac{0 - (-3) }{4 - 5}[/tex]

                = [tex]\frac{3}{-1}[/tex]

                = -3

By substituting x, y, and m values in the equation we can get the value of c.

Consider x = 4 , y = 0, m = -3

y = mx + c => 0 = (-3)4 + c

                      c = 12

Therefore, the slope-intercept form of (5,-3) and (4,0) is y = -3x + 12.

is it true that the discriminant of f(x)=2x^2-10x+8 equals -36? (algebra 2)

Answers

The discriminant of the equation f(x) = 2x^2-10x+8 [tex]\neq[/tex] 36

To find out the discriminant of f(x)=2x^2-10x+8

The formula for the discriminant is represented by b²-4ac.

This equation is in general form, which is ax² + bx + c = 0.

So, lets assume the values to be

a = 2

b = -10

c = 8

The discriminate that we need to find out in the equation below is

D = b²-4ac

[tex]D = -10^{2} - 4(2)(8)[/tex]

D = -100 - 64

D = -164 which is not a nice number

As the discriminant had a negative value of -164.

This means there are no real solutions to the equation, because the discriminant is negative.

Hence the discriminant of the equation f(x) = 2x^2-10x+8 [tex]\neq[/tex] 36

combine a terms:

-a - 5 + 3b - 2 - 2b

combine b terms:

-a - 5 + b - 2

combine numbers:

y = mx + b, solve for m

subtract b from both sides:

y - b = mx + b - b

y - b = mx

Sarah can text 91 words in 14 minutes. At
this rate, how many minutes would it take
her to text 65 words?

Answers

If Sarah can text 91 words in 14 minutes, then at this rate she will type 65 words in 10 minutes

Number of minutes to types 91  words = 14 minutes

Here we have to use the unitary method to solve the problem

Time taken to type 1 word = Number of minutes to types 91  words / 91

Substitute the values in the equation

= 14  / 91

= 2 / 13

Time taken to type 65 words =  Time taken to type 1 word × 65

Substitute the values in the equation

= (2/13) × 65

= 10 minutes

Hence, if Sarah can text 91 words in 14 minutes, then at this rate she will type 65 words in 10 minutes

Marks
5 cm

Answers

The total surface area of this prism is: 620 cm².

How to find the total surface area?

First step it to find the Area of isosceles triangles:

Area of isosceles triangles = [(24 × 5) ÷ 2]

Area of isosceles triangles (120 ÷ 2)

Area of isosceles triangles = 60 cm²

Second step is to find the area of 2 triangles

Area of 2 triangles = 60 cm² × 2

Area of 2 triangles = 120 cm²

Third step is to find the Area of 2 identical rectangles

Area of 2 identical rectangles= (10 × 13 ) × 2

Area of 2 identical rectangles=  260 cm²

Fourth step is to find the  bottom area of rectangle

Area of rectangle  = 24 × 10

Area of rectangle = 240²

Now let find the total surface area

Total surface area =120 + 260 + 240

Total surface area = 620 cm²

Therefore the surface area is 620 cm².

The first option Focus(2,-0.5); directrix x=0 of the parabola is the correct answer.

What is a parabola?

A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line.

The general equation of a parabola is as follows:

[tex](y-k)^2=4a(x-h)[/tex]

Now, consider the given equation.

[tex](y+0.5)^2=4(x-1)[/tex]

Now, compare with the standered equation.

a=1, k=-0.5 and h=1

Here, a is positive hence, the parbola opens right side.

Focus is given by the following coordinate:

[tex](h+a,k)=(1+1,-0.5)\\=(2,-0.5)[/tex]

Now, equation of diretrix is given by the following expression:

[tex]x=h-a\\x=1-1\\x=0[/tex]

Hence, the first option Focus(2,-0.5); directrix x=0 is the correct answer.
